Could you write a formal proof of this?
2. Given: 2x -4 = 6x - 8 Prove: x = 1 , it has to be in the Statements/Reasons column form

Answer 1

Explanation:

2x - 4 = 6x - 8 Given. Add 8 to both sides

2x - 4 + 8 = 6x - 8 + 8 Equal Addition Property for Equations.

2x + 4 = 6x Combine like terms.

2x - 2x + 4 = 6x - 2x Equal Subtraction Property for Equations

4 = 4x Divide by sides by 4

4/4 = 4x/4 Equal Division Property for Equations

1 = x Combine like terms.
